Product Description
Regalite™ C6100 hydrocarbon resin is a very light color, partially hydrogenated, modified aliphatic resin designed as an excellent tackifier for the midblock of thermoplastic block copolymers, including styrene-isoprene-styrene (SIS), [low, medium, and high styrene content] styrene ethylene butylene styrene (SEBS) and styrene-butadiene-styrene (SBS). It also shows excellent compatibility with ethylene vinyl acetate (EVA). Regalite™ C6100 is recommended for use in a variety of hot melt adhesives, including nonwoven assembly, packaging, bookbinding, glue sticks, and pressure-sensitive tape and label adhesives.

Due to the thermoplastic behavior, pastillated and half-ball resins may fuse, block or lump. This can be accelerated under any of the following conditions: 1) above ambient temperature, 2) prolonged storage, 3) pressure, e.g., stacking pallets, or a combination of these conditions. This is particularly applicable for low softening point resin grades. It should be noted that lumping does not have a negative impact on the product specifications. Due to the nature of the product, claims regarding lumping cannot be accepted.

When stored in accordance with the MSDS, in it''s original unopened container in an enclosed area and protected from moisture, extreme temperatures and contamination, this product (in solid form only) is estimated to continue to meet applicable sales specifications for more than 2 years from the date of manufacture. First in first out inventory control is recommended.
